Here's some comments by "Pete Bown MPhys(Hons), DipEd, GradInstP, LRPS" in his guestbook, that you might get a chuckle out of:

"Pete Bown: As you say, the Moon doesn't have an atmosphere. But, the temperature is below -20 Celcius during daylight. The Moon can not be hotter than the Earth as it is the same distance from the Sun and receives the same amount of energy. There is no atmosphere to generate a greenhouse effect to raise the temperature to the same level as Earth. The Kodak film used would have shattered. Heat can stil be dissipated by radiation, that's how we get heat from the Sun.

Pete Bown: Try blowing into a bag of flour. In a vacuum a blast of gas will not cloud diffuse or billow out like an aerosol, it will form a jet. The path will only be disturbed by gravity or an object in it's way. On the Moon the blast from a decending rocket would form a pattern."

There's more. But I don't know how many I can get away with producing here.
